Answer:
3 because 3 x 2 + 3 x 8 = 30 and 3(2+8)=30
Answer:
Relative minima at , and relative maxima DNE.
Step-by-step explanation:
The given function is f(x) = x (x + 7) ...... (1)
We have to calculate the relative maxima and relative minima at point (x, y).
Rearranging the function given above we get.
⇒
Now, this is an equation of parabola having vertex at and the axis is parallel to positive Y-axis.
Therefore, the function(1) has a relative minima at , and the relative maxima DNE. (Answer)

A graphing calculator can show you a graph of each expression, which you can compare to the offered choices.
_____
You can make use of the relations ...
... sin(a)+sin(b) = 2sin((a+b)/2)cos((a-b)/2)
... cos(a)+cos(b) = 2cos((a+b)/2)cos((a-b)/2)
... cos(a)-cos(b) = -2sin((a+b)/2)sin((a-b)/2)
Then you have ...
and ...
The answer is 7. That's the answer
